Overview

pnpm is a Fast, disk space efficient package manager

Affected versions of this package are vulnerable to External Control of File Name or Path through the handling of reserved or malformed bin names during global package operations. An attacker can cause deletion of critical directories outside the intended global bin directory by publishing a malicious package with specially crafted manifest bin keys and then triggering global remove, update, or add-replacement flows.
